Quartersawn material is reported to degrade to a lesser degree. Partial air-drying before kiln-drying has been recommended Tree Size Tree height is 30-40 m Tree height is 40-50 m Boring Fairly difficult to very difficult Cutting Resistance Fairly Difficult to Very Difficult to saw Response to Hand Tools Fairly Difficult to Difficult to Work Difficult due to interlocked grain and medium density Steam Bending Can be bent to a radius of ,6 inches (15 cm) Numerical Data Item Green Dry English Bending Strength 11956 20776 psi Crushing Strength 1073 1945 psi Density 60 lbs/ft3 Hardness 2528 lbs Maximum Crushing Strength 6056 11760 psi Shearing Strength 2323 psi Static Bending 7438 13132 psi Stiffness 2117 2891 1000 psi Toughness 230 inch-lbs Specific Gravity 0.65 0.79 Item Green Dry Metric Bending Strength 840 1460 kg/cm2 Crushing Strength 75 136 kg/cm2 Density 961 kg/m3 Hardness 1146 kg Maximum Crushing Strength 425 826 kg/cm2 Shearing Strength 163 kg/cm2 Static Bending 522 923 kg/cm2 Stiffness 148 203 1000 kg/cm2 Toughness 264 cm-kg References Bolza, E., Kloot, N.
